为 MAC 在 R 4.0.3 中加载 SDSFoundations package 时出错

Question

I installed R on my mac (Version 4.0.3) and after this, I downloaded the SDSFoundations package to the desktop (.tar file). I installed the package with the following command: install.packages("~/Desktop/SDSFoundations_1.1_R_x86_64-apple-darwin10.8.0.tar", repos = NULL, type = 'source') [I added the 'type = 'source' because I was getting an error that repos = NULL could not be used with type = 'binary'] The package installed successfully.

PROBLEM: when I tried to load the package with library(SDSFoundations) I am getting the error: package or namespace load failed for 'SDSFoundations': package 'SDSFoundations' was installed before R 4.0.0: please re-install it

.libPaths() points to /Library/Frameworks/R.framework/Versions/4.0/Resources/library find.package("SDSFoundations") gives me /Library/Frameworks/R.framework/Versions/4.0/Resources/library/SDSFoundations

I do not understand what I am doing wrong. R 4.0.3 is the first R version I have ever installed on this system and right after this, I installed the SDSFoundations package. I do not understand why I am not able to load the package. Please help!

Answer 1

So the past few days, I had the same problem and when I hit the

installed_packages()

SDSFoundations -------- "3.2.3"

it showed me that SDSFoundations never upgraded from R 3.2.3.

The best thing to do is install the R version before 4.0.0 side to side with your newer versions and you can shift to the versions in the Rstudio. To be precise open the window from the TOOL/Global Options..., and from that window, you can choose your desired versions from the tool RGeneral/R version. At last, it will ask you to restart the Rstudio every time you change it but in the end, it worked perfectly for me. Hope this will help anyone who needs this info. ;)
